RaDAR – Digital modes and Smartphones

Digital devices are becoming more and more part of amateur radio and in particular for the RaDAR operator. There are applications available for Android devices. A list of my favourites (Amongst others) are:

Echolink – A client program that can be used to access Echolink enabled repeaters and simplex links anywhere in the world. It can be used much like using a handheld. A mic / earphone system can be used for convenience.

Morse decoder – A digital modes program used to decode morse code heard over the radio using either speaker to mic or a dedicated sound card interface to the radio.

AKA – A digital modes program used to transmit morse code over the radio using either speaker to mic or a dedicated sound card interface to the radio. The program makes use of parameters and the results like GPS position can be converted to morse code and sent over the air. Very handy when used as a pre programmed morse keyer. It has a beacon function too!

DroidRTTY – A digital modes program used to decode RTTY heard over the radio using either speaker to mic or a dedicated sound card interface to the radio. RTTY can be generated and transmitted using VOX / MOX on the rig.

DroidPSK – A digital modes program used to decode PSK heard over the radio using either speaker to mic or a dedicated sound card interface to the radio. PSK can be generated and transmitted using VOX / MOX on the rig.

AndPSKMail – A digital modes program specifically written to work with PSKMail servers around the world using either speaker to mic or a dedicated sound card interface to the radio.

HamGPS – An excellent GPS utility used to determine position in Latitude / Longitude or a grid locator even to more than 6 digits! It can determine direction to another grid, handy for orientating yagi antennas while in the field.

APRSDroid – This application uses the cell network to communicate with APRS servers on the Internet. Good where there are no APRS SatGates or IGates nearby or within range.

Endomondo – This is a sportman’s training application but can be used for RaDAR too. It shows the track travelled on Google maps. It shows distance and speed and the information can be shared with others via Facebook. A nice way to let people or hams know exactly where you’ve been.

GPSEssentials – Many tools and widgets that can be set for your particular applications. Ideal for RaDAR recces where photos can be taken and positions recorded on a map for later viewing of the environment.

DTMF – This is a handy utility where DTMF signaling is required and your rig does not have a DTMF microphone or other facility.

Last but not least.

ElectroDroid – This is an absolute must for every ham or home brewer. It also has a simple circuit simulator that will get the young ones interested in electronic circuits.

Many of these applications have a small charge but are worth every cent and one contributes to the advancement of the digital modes development within amateur radio.
